Comparative evaluation of the single-phase “VIENNA I” and the Double Boost effect “DBE” rectifiers under sliding mode current control

This paper deals with a comparative evaluation of the single-phase “VIENNA I” and the “DBE” rectifiers. Their cores respectively involve one and two coils. They operate in continuous current and PFC modes thanks to an AC side current control. The two coils allow to get a “Double Boost Effect” during each half-period of the mains, then transmitting the stored energy to both DC capacitors. This is not possible to get it with the “VIENNA I” rectifier. In order to demonstrate it, an itemized analysis is performed. Then the simulations and experimental results are done.
